CONDOR (Chilean ObservatioNs of DrOught chRonologies)

Overview

This repository contains tree ring data and associated hydroclimatic observations that can be used to study drought impacts.

Getting Started

1. Download the example data from https://github.com/jevegabriones/CONDOR
2. Load the digitalized tree-ring example in RStudio using the ".jpg" and ".Rdata" files containing the tree-ring points detected.
3. Load the identified tree rings in RStudio using the provided Rdata file.

Dataset Description

The dataset includes the following observations, ERA5 basin averages, and PCR-GLOBWB2.0 model basin averages:

• Temperature (ERA5-Land Monthly Aggregated - ECMWF Climate Reanalysis, Muñoz Sabater, J., 2019)
• Precipitation (ERA5-Land Monthly Aggregated - ECMWF Climate Reanalysis, Muñoz Sabater, J., 2019)
• Groundwater observations (Venegas et al., 2024)
• Surface water observations (CAMELS-CL, Alvarez-Garreton et al., 2018)
• Potential evapotranspiration (Penman-Monteith, ERA5 global reanalysis Monthly Aggregated - ECMWF Climate Reanalysis, Hersbach et al., 2020)
• Soil moisture (CCI-SM, Preimesberger et al., 2021)
• Groundwater recharge (PCR-GLOBWB2.0, Sutanudjaja et al., 2018)
• Baseflow (PCR-GLOBWB2.0, Sutanudjaja et al., 2018)
• EVI (MODIS/Terra and Aqua Surface Reflectance Daily L2G Global 1 km and 500 m, Didan, K., 2015)
